RE: Flyback Transformer Boards - Any interest ? ? ? ?

When i tried push pull to drive a flyback it was absolutley aweful!!!  I 
must say, dont use push pull!  The mosfets got insanely hot and the flyback 
didnt make very good sparks.  Im now using a half bridge (with a gate 
isolation transformer and all!) to drive just about any flyback with more 
power than you will ever need.  Though, it wont drive ignition coils due to 
the high frequency gate transformer.
